Inmate Fight at Idaho Maximum Security Triggers Prison Lockdown

The Idaho Maximum Security Institution, part of the Idaho Department of Correction prison complex south of Boise, remained on lockdown Sunday after a fight erupted involving between eight and 10 inmates.

IDOC officials said the fight began in the afternoon on Saturday, June 11. When inmates didn't respond to correctional officers' commands, guards used gas and so-called "sting-ball" rounds to quell the incident.

The melee occurred in the maximum security prison's A-3 tier, which houses 64 inmates. The entire IMSI facility houses up to 400 inmates.

During the lockdown, all inmates are restricted to their cells. Prison officials said no inmates or staff suffered serious injuries. Meanwhile, IDOC Director Kevin Kempf has ordered a Serious Incident Review to detail exactly what happened.
